Fundal Height Calculation:
From: | To: |
Fundal height measurement is a method used during pregnancy to assess fetal growth and development. It measures the distance from the pubic bone to the top of the uterus (fundus) in centimeters.
The calculator uses a simple correlation:
This approximation is most accurate between 20-34 weeks of pregnancy.
Details: Regular fundal height measurements help monitor fetal growth, identify potential issues like intrauterine growth restriction or polyhydramnios, and track pregnancy progression.
Tips: Enter the number of weeks since your last menstrual period. The calculator will estimate the expected fundal height measurement.
Q1: How accurate is fundal height measurement?
A: While useful for tracking trends, fundal height measurement has limitations and can vary based on maternal factors like BMI, fetal position, and amniotic fluid volume.
Q2: When should fundal height measurements begin?
A: Typically around 20 weeks gestation, when the fundus reaches the umbilicus. Before this time, measurements may not be reliable.
Q3: What if my fundal height measurement differs from expected?
A: Variations of 2-3 cm are usually normal. Significant differences may warrant further investigation with ultrasound.
Q4: Can fundal height predict delivery date?
A: While it correlates with gestational age, fundal height is not a precise method for predicting delivery date.
Q5: Are there factors that affect fundal height accuracy?
A: Yes, including maternal obesity, multiple gestation, uterine fibroids, fetal position, and amniotic fluid volume.
